The Stray (2016)

1966, United States of America: Kennedy is unable to prevent the Cuban Missile crisis in 1962, creating a nuclear winter throughout the country that seems to have no end. Our nations structure collapses, our nations defenses fall and our nations people suffer from severe radiation poisoning, mutating them into ghoulish, flesh eating monsters. Tracey Arnold, the man with no direction, struggling to accept his actions and live with himself, travels through this barren wasteland at a constant battle with his humanity, and the Stray that refuses to let him forget.
